Abstract:
A hydraulic control apparatus includes a switching device that switches between a hydraulic servo of the plurality of hydraulic servos of the first friction engaging element and a hydraulic servo of the plurality of hydraulic servos of the second friction engaging element so as to supply a control pressure from the one pressure regulating solenoid valve to each of the plurality of hydraulic servos, wherein the switching enables a control of an engagement and disengagement of the first friction engaging element and the second friction engagement element using the one pressure regulating solenoid valve.
